I agree 100%. I assume studies are being done but they simply havent been around long enough to have the same amount of type of data that cigarettes have.
I vape after quitting real cigarettes about 9 months ago. I occasionally still smoke real ones - if I drink I usually buy a pack and smoke whatever is left over over the course of the week. I'm not a diehard vapor, cloudchaser, blah blah blah. I use it because I assume / hope that they are better than real cigarettes but I'm thoroughly annoyed with people who are like, "Vaping is healthy - vape all day!" I would be very surprised if there aren't some problems with the ecig in terms of health. I think people are pretending they don't exist but for anyone that is looking forward to vaping for the rest of their life is going to be disappointed in a couple years when some real data shows up.
